Be it known that I, Bnmmm 8. Brass, of Pekin, in the county of Tasewell,State of Illinois, have invented a new and improved Sash-Fastener; and Ido hereby declare that the following is a full, clear,.and

exact description thereof, which will enable .others skilled in the artto make and-rise the same, reference being bad to the accompanyingdrawings, forming part of this specification.

Thenature of my invention consists in the peculiar construction of afriction wheel, which is made to bear i 'upon thefsides of a sash so asto hold it in any desired position; it is also-provided with a smallpinion, which meshes into and works in an inclined corresponding rack,which is made fast to the window-frame.

To enable others skilled in the art-to make and use my invention, I willproc'eed'to describe its construction Figure 1 is a longitudinalsectional elevation from the line a: 2;. Figure 2 is a front elevation'of the same. 7

Figure 3 is also a longitudinal sectional elevation of another device,merely shown to anticipate figs. 1 and 2.

Figure 4 is alsoa front elevation of fig. 3, and for the same purpose.

Letters of like name and 'kind refer to like parts in each of thefigures.

A. represents a small wheel, made of metal and provided with teeth npouthe end at the periphery. The body of the wheel is cored out so that itis but little more than a rim. It is fitted into a slotted plate, B,which is fastened to the window-frame. Upon the inside of this plate, B,is secured another plate, 0, in which is a rack which corresponds withthe pinion A. This plate and rack G is inclined up from theplate B. E isa trigger that passes through and has a bearing in the plate F. Thetrigger, E, is provided with a dog that works within the wheel A. Theperiphery of this wheel, A, is corrugated so that it will engage theedge of the sash more firmly.. The wheel in figs. 3 and 4 is providedwith a small pinion upon the shaft with teeth, instead of being at theend at the periphery.

The operation consists in simply raising the sash, which rolls the wheelA up the incline and lets the sash move up without any friction orresistance to the sash; but when the force that is applied to raise thesash is withdrawn, the weight-of the sash draws the wheel down theincline by the friction of the corrugations upon the periphery of thewheel against the edge of the sash holds it up and at any point desired.When it is desired to lower the sash, by beating down on the triggerthrows the wheel up the incline into a wider space and disengages thesash so that it can be let down at will. Various means have been devisedand applied to sashes for the purpose of holding them in a certainposition, but thus far have not been reliable, and either cumbersome orfrail, therefore of but little utility. But by my invention I am able toobviate and overcome all the dificulties and objections urged againstthe more common means that have been introduced, and to a certain extentemployed, for the purpose of holding window-sash in a certain position,by substituting a neat and comely device which is durable and not likelyto wear and get out of order, thereby rendering it of great use andutility.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The catch E, operating within the toothed roller A, in combination withthe plate F, inclined toothed back 0, and toothed roller A,substantially as herein shown and described, and for the purposespecified.

The above specification of my invention signed by me this 20th day ofJune, 1863.
